specific Embodiment 1

[0024] see figure 1 It can be seen that the yak fermented feed for improving growth performance of the present invention has 50 parts of coriander root as the main raw materials, 10 parts of highland barley, 10 parts of wheat bran, 20 parts of cottonseed meal, 10 parts of stems and leaves of Astragalus membranaceus, and the main raw materials are also added with fermentation bacteria. The bacteria are Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria mixed strains, and the addition ratios of Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria mixed bacteria are Bacillus subtilis 1‰, Saccharomyces cerevisiae 2‰, mixed lactic acid bacteria 2‰, and mixed lactic acid bacteria are Streptococcus faecalis and Lactobacillus acidophilus, the addition ratio of Streptococcus faecalis and Lactobacillus acidophilus is 8:2, when fermenting 1kg of main raw materials, add 1g Bacillus subtilis, 2g yeast, 1.6g Streptococcus faecalis, 0.4 g Lactobacillus aci...

specific Embodiment 2

[0025] see figure 1 It can be seen that the preparation method of the yak fermented feed that improves growth performance is characterized in that the processing steps are as follows: Step 1: strain activation: Bacillus subtilis and saccharomyces are activated by adding water according to the ratio of 1g:100mL for 0.5h respectively, and lactic acid bacteria are cultivated in MRS liquid basal culture, the activation time of strain activation is 0.5h, the fermentation time is 5d, the temperature is controlled at 30°C, and the initial moisture is 35%; Step 2: inoculation and fermentation: coriander root, wheat bran, highland barley, cottonseed meal, stem and leaf of Astragalus membranaceus Grind to 30-50 mesh, mix evenly in proportion to become the primary material, add the primary material to Bacillus subtilis, Saccharomyces cerevisiae, Streptococcus faecalis, Lactobacillus acidophilus in proportion, and mix well; Step 3: Cover the film : Fully mix the strains and fermentation r...

Abstract

The invention discloses fermented feed capable of improving growth performance for yak. The fermented feed is characterized by being prepared from the following main raw materials in parts by weight:45-55 parts of common turnips, 5-15 parts of highland barley, 5-15 parts of wheat bran, 15-25 parts of cottonseed meal and 5-15 parts of astragalus stems and leaves. The fermented feed can sufficiently and effectively help animals to digest plant raw materials and improve the digestion, absorption and utilization rate of the plant raw materials; protein is degraded into amide and amino acids by fermentation, nitrogen-free extract of carbohydrates is converted into lactic acid, so fibers in the feed are softened up and the rumen burden of the yak is relieved; the content of astragalus polysaccharides and astragaloside in the astragalus stems and leaves is increased after fermentation, and polysaccharide substances on the cell surfaces of saccharomycete can adsorb mycotoxins in the feed; theefficiency of feed utilization is improved and the growth performance is enhanced; and the content of nutrients and functional components in the common turnips, such as crude protein, total sugar, reducing sugar, total acids, flavones, total phenols, triterpene and polysaccharides, can be effectively improved after fermentation, so the hypoxia tolerance time of animals is effectively improved.

Description

technical field [0001] The invention relates to the field of feed production, in particular to yak fermented feed for improving growth performance. Background technique [0002] Yak is an irreplaceable biological species in the Qinghai-Tibet Plateau and pastoral areas in northwestern Sichuan. It is an important means of production, a pillar industry of the national economy in the region, and a basic industry that the majority of herdsmen rely on for generations to survive and develop. [0003] However, due to the slow acceptance of advanced management concepts in the local area, there is no concept of supplementary feeding and fattening for the feeding and management of yaks, and only local characteristic vegetation coriander roots are fed. Therefore, the growth of yaks is slow and the slaughter rate is low. Fermented feed has been widely used in the breeding process of economic animals in the inland area, which is conducive to improving the utilization of animal diets, impr...
